The selection of welding wire in aluminum alloy is mainly based on the type of base material, and the requirements of joint cracking resistance, mechanical properties and corrosion resistance are comprehensively considered. Sometimes when a certain item becomes the main contradiction, the selection of welding wire focuses on solving this main contradiction and takes into account other requirements.

Under normal circumstances, welding aluminum and aluminum alloys are used with the same or similar composition of the base metal welding wire, so that better corrosion resistance can be obtained; However, when welding heat treatment to strengthen aluminum alloy with a large tendency to crack, the selection of welding wire is mainly started from solving the crack resistance, and the difference between the composition of the welding wire and the base metal is very large.
